In the main event of ONE: Reign of Dynasties, reigning ONE Strawweight Muay Thai and Kickboxing World Champion Sam-A Gaiyanghadao of Thailand successfully retained his Muay Thai World Title behind a near-flawless performance against ISKA K-1 World Champion and number one ranked contender Josh “Timebomb” Tonna of Australia.
Sam-A appeared composed and relaxed to start the bout, delivering a volley of fast boxing combinations and high round kicks in the first round.
In the beginning of the second, Sam-A dropped Tonna with a bullet-like left straight, sending the Australian to a mandatory 8-count. Sensing he had his opponent hurt, Sam-A poured on the pressure and dropped Tonna two more times en route to a technical knockout victory.
